Engineering Technician

Join to apply for the Engineering Technician role at Cocoon. At Cocoon, we’re developing low‑carbon construction materials for the builders of tomorrow. Delivering our technology at demo‑plant scale requires extensive hands‑on engineering work: building, installing, commissioning, and operating equipment that enables testing and material generation in real‑world conditions. This role is central to delivering and scaling our technology.

You’ll drive implementation and delivery for the engineering team, building test rigs, installing equipment at partner sites, and supporting trials in the UK and USA as we scale towards building a permanent plant.

The Role

We’re looking for an Engineering Technician to build, install, and operate prototype equipment and test rigs that support Cocoon’s R&D and material generation programmes. You’ll work closely with engineers, scientists, and operations teams to deliver trials safely, on time, and to specification, often in challenging industrial environments. This is a highly practical, travel‑heavy role involving mechanical build, electrical wiring, hydraulics, commissioning, troubleshooting, and trial execution. You’ll spend significant time travelling, supporting test campaigns, and installing equipment at partner locations in the UK, Europe, and the US.

Responsibilities

• Build test rigs and prototype equipment to agreed designs, timelines, and quality standards.
• Install, commission, and operate equipment at Cocoon test sites and partner facilities in the UK and abroad.
• Carry out tests under the direction of a test engineer and report findings.
• Upgrade and modify test rigs with new hardware, controls, instrumentation, or mechanical components.
• Suggest process and hardware improvements and be a key source of information for the R&D and process engineering teams.
• Support extended test campaigns in the UK and overseas, including driving Luton vans, completing risk assessments, and working outdoors in challenging industrial environments.

Mechanical, Electrical and Workshop Work

• Perform mechanical, hydraulic, and pneumatic assembly of prototype equipment.
• Wire automation cabinets, sensors, actuators, pumps, and 3‑phase systems.
• Read and interpret manufacturing drawings, wiring diagrams, and process diagrams.
• Carry out light machining and fabrication (cutting, drilling, grinding, welding, bending, pipe joining).
• Create components using additive manufacturing techniques.
• Order service parts, manage workshop organisation, and support general site readiness.

You’ll Succeed In This Role If You…

• Have extensive, hands‑on experience as an engineering technician in a related industry.
• Are confident with mechanical build, basic electrical installation, hydraulics, and troubleshooting.
• Can work independently on targets while collaborating closely with engineers and scientists.
• Are proactive, dependable, safety‑conscious, and driven to solve problems.
• Are willing and able to travel extensively and work extended hours during test campaigns.

Bonus Qualities

• Knowledge of industrial automation, instrumentation, and PLCs.
• Welding qualifications, especially TIG for stainless steel.
• Forklift qualification or experience operating heavy equipment.
• Electrical installation or wiring qualifications.
• Experience working with foundries or high‑temperature process equipment.

What We Offer

• A hands‑on role at the centre of Cocoon’s engineering and scaling journey.
• The opportunity to work on first‑of‑a‑kind test rigs and prototype equipment.
• Extensive travel and exposure to world‑class industrial partners and test facilities.
• Clear progression opportunities toward workshop lead, supervisor, or test engineer roles.
• A mission‑driven team working to support the transition to Net Zero.
